QML (JavaScript) how to create dynamic object?

Kycho

The createRoom function does not work.
What I want is to create a Dynamic Room object inside the RoomPage.

How can I solve this problem?

RoomSelect.qml

import QtQuick 2.4

RoomSelectForm {
    function createRoom(id,name,type,price,visible){
        var component;
        var object;
        component = Qt.createComponent("Room.qml")
        object  = component.createObject(roomPage2.roomLayout,{"x":0 , "y" : 0});
        object.roomId = id;
        object.roomName = name;
        object.roomType = type;
        object.roomPrice = price;
        object.roomVisible = visible;
        return object;
    }
}

RoomSelectForm.ui.qml

import QtQuick 2.4
import QtQuick.Controls 2.3
import QtQuick.Layouts 1.3

Item {
    id: item1
    property alias roomPage2: roomPage2

// blablablabla...

        SwipeView {
            id: swipeView

            RoomPage{
                id:roomPage1
            }
            RoomPage{
                id:roomPage2
            }
            RoomPage{
                id:roomPage3
            }
    }
}

RoomPage.qml

import QtQuick 2.0
import QtQuick.Layouts 1.3
import QtQuick.Controls 2.2

Item {
    property alias roomLayout: roomLayout

// blablablablabla...

        GridLayout {
            id: roomLayout
        }
}

Room.qml

import QtQuick 2.4

Item {
    property int roomId: -1
    property alias roomName: roomName.text
    property alias roomType: roomType.text
    property alias roomPrice: roomPrice.text
    property alias roomVisible: room.visible

Rectangle{
// blablablablabla...
}

}

Does not work means ? What is the behavior ? You are creating local variable. Did you observe that ?

Sorry.
Some content is missing.

I want to call the createRoom function in C ++.

main.cpp

    QQmlEngine *engine = ui->quickWidget->engine();

    QQmlComponent qml_RoomSelectCom(engine,QUrl("qrc:/RoomSelect.qml"));

    QObject *qml_RoomSelectObj = qml_RoomSelectCom.create();

    QVariant qml_rooms;

QMetaObject::invokeMethod(qml_RoomSelectObj,"createRoom",Q_RETURN_ARG(QVariant,qml_rooms),Q_ARG(QVariant,5),Q_ARG(QVariant,"Test"),Q_ARG(QVariant,"wqe"),Q_ARG(QVariant,"1230"),Q_ARG(QVariant,true));

The createRoom function is executed but the Room object does not appear on the screen.
I think the use of this invokeMethod function seems to be wrong.

How can I solve it?
